More ways to buy from you.
More sales for you.

Let your customers vend by chatting on WhatsApp — the app they already live in, no download, no login, just plain language. And when they've run out of data, a USSD code keeps the sale alive. Meet them where they already are.

The quiet leak

A checkout they can't reach is a sale you never make.

Your website only works when a customer is online and willing to log in. Miss either — no data, or just no patience — and the sale quietly slips away. VendStack adds the channels they already reach for: a WhatsApp chat, and a USSD code that works even when their data runs out.

Buy without leaving WhatsApp

Customers vend right inside the app they already open all day — no new app to install, no account to log into.

smart_toy

Just say what you want

Plain language: “send mtn 2gb to my brother.” The AI understands it, shows a clear summary, and confirms with a PIN.

dialpad

Sell even when data runs out

A USSD dial code lets customers buy with zero data — so a flat wallet or an expired plan never means a lost sale.

Your money, your rules

You own the wallet, pricing and vending logic. We orchestrate the channels — we never touch the funds.

Go live in three steps

Stay ahead. Vend smarter.

Connect your backend

Point us at your wallet with a handful of small API endpoints. We sign every request so you can trust it.

Turn on your channels

Flip on USSD and WhatsApp from the dashboard. We handle Meta and the dial-code wiring for you.

Customers just vend

They chat or dial, confirm with a PIN, and get value instantly. You watch it land in real time.

Built for multi-brand merchants

One account. Every website you run.

Most merchants run more than one platform. Add all of them to a single VendStack account, switch between them in a click, and fund every one from a single shared wallet — separate channels and reporting, one place to manage it.
